Common feature is identified by identical appended drawing reference between different embodiments of the invention.In reference particular implementation of the invention
In the case where example, which is identified with appended drawing reference.
Referring to Fig.1, device 10.1 includes rotor 12, and rotor 12 is supported for along direction of rotation around approximate horizontal rotary shaft
Line 14 rotates.Rotor 12 is supported by support construction (not shown in figure 1), and it can be around the axis extended along rotation axis 14
In the upper rotation such as boss or bearing.Rotor 12 can be mechanically connected to an infinite number of slave unit, and slave unit can connect from rotor
Rotating energy is received to execute useful function.For the rotary power from rotor 12, it will be appreciated by those skilled in the art that it is used
The diversity on way, but as non exhaustive example, including driving mechanical machine, such as capstan winch, pump etc., and including for inciting somebody to action
Rotary power from rotor is converted into the driven generator or similar machine of electric power.The output of these machines can apply immediately

Rotor 12 includes 30 hollow components in 18 form of pipe, this 30 hollow components be arranged to rotor its
Remaining part point rotates together, and pipe is mounted between two spoke wheels 20 and its end cap 21 is closed.Each pipe 18 has cylinder
Shape outer wall 22 and chamber is limited on the inside of it.
The shape and structure of rotor 12 and its device for limiting chamber can vary greatly, for example, chamber can form one
A entirety can have any amount of chamber and be not only two, and hollow component of different shapes can be used to form chamber etc..But
It is that at least some chambers must be limited on the different radial rotaries relative to rotation axis 14 along direction of rotation 16, and excellent
Selection of land, at least two chambers should be limited on the opposite side of axis-and it preferably but is not generally radially opposite.Preferably, rotor
A large amount of chambers should be limited, and these chambers should be uniformly distributed (circumferentially spaced) around rotation axis 14.
Each pipe 18 (and therefore each chamber in pipe) is spaced apart with rotation axis 14, but some pipes-are with bigger
Radius is spaced apart with axis.
Even if the part of the restriction chamber of rotor 12 can have various constructions, but the use of pipe 18 be for this purpose preferred
, because the cost of manufacture rotor is low, using commercially available pipe, longitudinal scalability of pipe avoids " dead space " between pipe from (seeing below
Text), and in every root canal operate longitudinal gap valve easy degree (seeing below).
Each pipe 18 has the uropore 24 longitudinally arranged, and uropore 24 prolongs along the direction opposite with direction of rotation 16 from the chamber in pipe

Pipe 18 is preferably spaced apart, to allow fluid to pass through between them and avoid dead space.Space between pipe 18
It may be decreased the efficiency of blade 26, because some fluids impinged on the buckets will be between pipe 18 by without on blade
Apply its complete impact potential.However, the fluid being discharged from uropore 24 may quilt in the case where not having space between pipe 18
Retention between the blades, and prevents the rotation of rotor.
The size of rotor 12 and the relative size of its component can change according to the operating parameter used when rotor.
Referring to Fig. 2, device 10.2 includes rotor 12, and rotor 12 has the rotation opposite with direction of rotation shown in Fig. 1
Direction 16.Pipe 18 is supported in spoke 28, but spoke does not form a part of wheel, and compared with the pipe of larger radius, this
The diameter of a little pipes is just smaller closer to rotation axis 14.The variation of pipe diameter be only intended to ensure around pipe 18 closer to rotary shaft
The enough free spaces of line 14, to prevent dead space.
Referring to Fig. 3 to Fig. 5, support the support structure configuration of each rotor 12 at support rotor, so that being optionally situated at
Above and below the boundary formed between the fluid of two kinds of different densities.The present invention is not limited to any fluids (or even to be not limited to
Compressible or incompressible fluid), but in most cases, it may be implemented for water as fluid of higher density,
Air is used as compared with low density flow, and the water surface is as the boundary between two kinds of fluids.In the case where not limiting the scope of the invention, under
Representative example of the text by reference water 34 and air 38 as high density and low density flow.
Support construction should be preferably configured to support rotor 12, so that it selectively, is preferably sequentially soaked completely
It is increased completely in air 38 not in water 34 and above the water surface.However, in some embodiments it may be preferable to,
The submergence of 12 holding part of rotor is to be used for its part or all of purposes.However, for the purposes of the present invention, rotation axis 16
At least it is located above and below the water surface 30 once in a while and is still necessary.
Rotor 12, which is sequentially supported on above and below the water surface 30, to be realized in various ways: it can be water level
Variation as a result, such as SEA LEVEL VARIATION due to caused by the tidal fluctuations of water level or wave action.However, it can also pass through tune
Section support construction (that is, being configured to promote and reduce the support construction of rotor 12), or come between self supporting structure and the water surface
Other relative motions-are for example, rotor can still be supported relative to the hull of water craft, when which floats in wave
It shakes.
Rotor 12 can operate in various patterns, comprising: submergence mode, wherein it is in submerged position, wherein preferably
Entire rotor is immersed in the water surface 30 in the following, as shown in Figure 3；Lift mode, wherein it is in raised position, wherein it is preferred that entire turn
Son is increased to above the water surface, as shown in Figure 4；And partially submerged mode, wherein the major part of rotor is respectively above the water surface
The lower section and.There is also other modifications on these operation modes, and wherein the water surface 30 can be any position relative to rotor 12,
But it needs to submerge at least to a certain extent by mass shift (mass displacement, as described below) operation rotor
And jack, and at least at minimum, rotation axis 14 should sequentially be immersed in below the water surface and increase
Above the water surface.
Referring to Fig. 3, for illustrative purposes, one in chamber 31 will be considered as " the first chamber " of rotor 12, and with the
The chamber 32 of one chamber diametrically will be considered as " second " chamber.However, depending on position-rotary shaft of any other chamber of rotor 12
The left or right side of line 14, these chambers will be operated in a manner of identical with the first chamber and the second chamber.
When rotor 12 initially submerges above the water surface 30, chamber 31,32 is respectively filled to a certain extent, preferably complete
It is filled entirely with air, and for purposes of explanation, it will be assumed that they are all completely filled with air.To simplify the explanation, it is assumed that the
One chamber 31 and the second chamber 32 have the same shape and dimensions, and they be spaced equal with rotation axis 14-this is shown
Situation in example, but the case where be not necessarily in other embodiments of the invention.
The uropore 24 of second chamber 32 is downwardly directed, so as to be held captured in second intracavitary for the second intracavitary air.Second
Air in chamber 32 is lighter than the water 34 around rotor 12, and therefore, the second intracavitary air applies upward buoyancy 36.
The uropore 24 of first chamber 31 is directed upwards towards, and air is escaped by uropore from the first chamber, and some weeks
The water 34 enclosed can enter the first chamber 31 by its uropore.Water 34 flows into the first chamber 31 and increases from the first chamber 31 discharge air
The gross density of first intracavitary content.Content in first chamber 31 can become completely from being made of completely air by water structure
At, or can be the mixture of air and water.The increase of first intracavitary content density reduces in water 34 around
The buoyancy of one chamber, and reduce by the upward buoyancy 35 of the content application of the first chamber.
Initially, when the first chamber 31 is full of air, the density of content is identical as the density of the second chamber 32, and by this
What the respective internal air of a little chambers 31,32 applied is in equilibrium state to buoyancy 35,36.However, in the first chamber 31
Tolerant density increases, therefore its buoyancy 35 is by reducing and the stronger buoyancy 36 from the second chamber 32 will occupy an leading position,
So that the synthesis difference between buoyancy will apply torque to rotor 12, rotate it along direction of rotation 16.
Depending on chamber and its definite physique of uropore 24, as shown in Fig. 3 to 5, each pipe on 14 right side of rotation axis
Chamber in 18, which can have the uropore upwardly extended and can be similar to the first chamber 31, to work.Similarly, rotation axis 14 is left
Each chamber in the pipe 18 of side can work as the second chamber 32.
Rotation of the rotor 12 along direction of rotation 16 can continue rotation turn around it is above, while air from pipe 18 chamber evolution
To the right side of rotation axis, until all air all escape and manage full of water, or until only remaining a small amount of empty in every root canal
Gas.In some embodiments, when some pipes 18 include to manage more air than other, rotation can terminate, and have more
The pipe of more air is located at the top of rotor 12, it is preferable that pipe and uropore 24 are configured to make rotor in several turns of rotor 12
Being rotated up to and air is discharged from chamber.
The air for escaping into (including the first chamber 31) on the right side of rotation axis from the uropore 24 of pipe 18 forms bubble, the bubble by
In they buoyancy and travel up to the water surface 30.However, if forming the dead sky that may capture these bubbles in rotor 12
Between, then the buoyancy of these bubbles will be such that blade 26 and/or pipe 18 drives up on right side against direction of rotation 16, turn to reduce
The efficiency of son 12.This is why preferably pipe 18 should be spaced apart, leaving space, bubble can pass through between them
These spatials are to the water surface 30.
For illustrative purposes and as shown in the picture, pipe 18 and its chamber surround 14 geometric mirror of rotation axis.However,
In other embodiments, the size of chamber, they can be with along the spacing of the radial oriented of direction of rotation 16 and they and rotation axis
As long as variation-is respectively flat in the left and right side of rotation axis around the combined moment of all volumes of the chamber of rotation axis 14
Weighing apparatus, and it is unrelated with the rotation of rotor 12.
Referring to Fig. 4, when rotor 12 is operated above the water surface 30 with its lift mode, for the ease of explaining, assume that
It has orientation same as shown in Figure 2, and when rotor initially increases below the water surface, chamber 31,32 each certain journeys of leisure
It is preferably entirely filled with water on degree, for purposes of explanation, it will be assumed that they are all completely filled with water.
The uropore 24 of first chamber 31 is directed upwards towards, so as to be held captured in first intracavitary for the first intracavitary water.First chamber
Air 38 weight of the water than surrounding rotor 12 in 31, therefore, the first intracavitary water applies downward gravity or weight 40.
The uropore 24 of second chamber 32 is downwardly directed, and water is escaped by uropore from the second chamber, and some surroundings
Air 38 can enter the second chamber 32 by its uropore.Air 38 flows into the second chamber 32 and reduces the from the second chamber 32 discharge water
The gross density of two intracavitary contents.Content in second chamber 32 can become completely from being made of completely water by air structure
At, or can be the mixture of air and water.The reduction of second intracavitary content density is reduced by the content of the second chamber
The downward gravity or weight 41 that object applies.
Initially, when the second chamber 32 is full of water, the density of content is identical as the density of the first chamber 31, and by these
The weight 40,41 that the respective internal water of chamber 31,32 applies is in equilibrium state.However, with the second chamber 32 content it is close
Degree reduces, therefore its weight 41 will reduce, and the heavier weight 40 from the second chamber 32 will occupy an leading position, so that weight
Between synthesis difference will apply torque on rotor 12, make its along direction of rotation 16 rotate.
Rotation of the rotor 12 along direction of rotation 16 can continue rotation and turn around above, while water is discharged to rotation from the chamber in pipe 18
The left side of shaft axis 14, until all water is all discharged and manages full of air, or until being only left a small amount of water in each pipe.
In some embodiments, when some pipes 18 include to manage substantially more water than other, rotation can terminate, and have more
The pipe of more water in the bottom of rotor 12, it is preferable that pipe and uropore 24 be configured to maximize the rotation of rotor 12 and from
Water is discharged in chamber.
The water of (including the second chamber 32) on the left of rotation axis is escaped under the effect of gravity to downlink from the uropore 24 of pipe 18
The water surface 30 is entered, and as the bubble referring to described in Fig. 3, if the water of discharge is trapped in the dead space in rotor 12
It then will work against direction of rotation 16 lower section driving blade 26 and/or pipe 18 to the left, to reduce the efficiency of rotor.However, discharge
Water can rotation by the space between adjacent tubes 18, without significantly affecting rotor.
Submergence and raised operation mode referring to Fig. 3 and Fig. 4 rotor 12 described depend on the quality of the chamber in rotor
Displacement, to drive its rotation, but mass shift needs fluid by uropore 24 while outflow and flows into.If uropore 24 is too
Small, the adverse current of this fluid, which will lead to one or two of fluid stream, to be become to throttle and insufficient quality position will occur
It moves.If uropore 24 is too big relative to the volume of the chamber in pipe 18, mass shift will by too fast and rotor 12 rotation
Prematurely stop (before enough air are discharged or before enough water is discharged).
Referring to Fig. 5, rotor 12 is shown as submerging the about one third of its height in water 34, and upper part 2/3rds is in sky
30 top of the water surface is protruded from gas 38.Rotor 12 can be driven as referred to Fig. 4 (in lift mode), due to previously with submergence or
Lift mode driving (as shown in Figure 3 and Figure 4) and may have spinning momentum, be likely to be at increase or submerge mode activated it
Between transition etc..
Water 34 can flow from right to left, as shown in figure 5, this is because gravity stream (such as river), come from wave action
Flowing and/or tidal current, and flowing water will impact submergence pipe 18, with drive rotor 12 along direction of rotation 16 rotate.
By the deployment tube 18 in blade 26, keep circulating water 42 more effective to the impact of rotor 12.
Similarly, empty when wind 44 is from left to right above the water surface 30 by pipe 18 and blade 26 above water level is impacted
Gas 38 can move, and driving rotor 12 is rotated along direction of rotation 16.But for more effectively the rushing to blade 26 using wind 44
It hits, if will be preferred on the pipe 18 that wind only impacts above the water surface 30.
Pass through 44 pairs of the wind pipes and leaf above the impact of 42 pairs of pipes 18 of water flow and blade 26 of 30 lower section of the water surface and the water surface
The impact of piece can occur only have one kind can be with one in (as shown in Figure 5) or both fluids simultaneously in the opposite direction
For simplicity, two kinds of fluid flowings are only shown in single figure for secondary flowing-.
Referring to Fig. 5 description the mode for driving rotor 12 rotate along direction of rotation 16 by fluid impact independently of submergence with
Raised operation mode (it depends on mass shift), and impact and operate and can individually or simultaneously grasp with mass transfer mode
Make.It is desirable that support construction is constructed such that the different operation modes of rotor 12 will drive it along identical direction of rotation, and
And for this purpose, water flow 42 and/or wind 44 can be redirected to drive rotor along identical direction of rotation 16, as quality turn
Mode shifter operation.
Referring to Fig. 6 to Fig. 8, other than uropore 24, each pipe 18 can also have preceding hole 46 in its opposite side, and preceding
Hole or all holes can be configured to open and close, for example, passing through valve.The valve of various configurations can be used, they can manually,
Semi-automatic or full-automatic mode operates.Preferably, the operation of valve is to be fully automated and remotely control, wherein mechanical
Actuating is influenced by rotor 12, for example, passing through the solenoid (not shown) being located on rotor 12.
Rotor 12 shown in Fig. 6 includes axis 58, and axis 58 has pulley 59 in its end, can be by belt etc. from pulley 59
Transmitting rotary power.
Fig. 7 shows pipe 18, and gating element 48 has tied up on pipe 18, the gating element 48 can along pipe longitudinal sliding motion, with
Public slot valve as a round 24,46 operates.Row's aperture of door 50 is limited in gating element 48, when the door is open, aperture of door 50 can
To be aligned with hole 24,46 or gating element can slide longitudinally, so that the angle in the hole 24,46 of aperture of door 50 and pipe 18 is misaligned,
And valve is closed.The simplicity structurally and operationally and single gating element 48 of the slot valve system can be operated by single solenoid with
The easiness for opening and closing all holes 24,46 makes slot valve be preferably suited for the present invention.
Fig. 8 shows the pipe 18 on each or its front aperture 24 and rear hole 46 with butterfly valve 52, and in pipe
Row's butterfly valve on side operates together with common push rod 54, which is connected to the individual crank arm of each butterfly valve
56。
Valve 48,52 allows that uropore 24 selectively closes off and preceding hole 46 is opened, allow rotor above with reference to Fig. 3 and
The operation of mass transfer mode described in 4, in addition to direction of rotation 16 will be inverted and preceding hole 46 will act as uropore.Therefore, preceding hole
It 24 and uropore 46 selectively opened and close the operation of rotor 12 is respectively allowed for invert under mass transfer mode.If water flow
42 or wind direction 44 changed, this can be used, for example, if water 42 and/or wind 44 are to the impact of blade 26 along opposite rotation
Turn direction 16 and drive rotor 12, then this reversion can be used, so that rotor also will be in the operation of mass shift mode along phase
Opposite direction driving.
Valve 48,52 also allows preceding hole 24 and uropore 24 to open on pipe, the pipe be discharged under submergence mode air or
Water is discharged under lift mode, fluid is allowed to flow into each chamber from side simultaneously and flows out each chamber from the other side, because
This increases the rate of air discharge or the rate of water is discharged from chamber, it may is that.This is only temporarily carried out, and
Pipe 12 is located at the side of the generation mass shift of rotor 12, and uropore 24 will be again switched off, and manages and be located at rotor there is no matter
Measure the side of displacement.Therefore, preceding hole 46 is periodically opened and closed with the rotation of rotor 12, and this of preceding hole follows
Ring operation can be influenced by simple mechanical device (such as cam of adjacent rotor).
Therefore, the ability for opening preceding hole 46 overcomes the difficulty as caused by fluid countercurrent current, and the adverse current, which can throttle, to be passed through
The flowing of uropore 24, as described above.In addition, the ability for selectively opening and closing preceding hole 46 means when needs are faster
It can be done so when mass transfer, but when needing slower mass transfer, preceding hole and/or uropore 24 can be complete or partial
Ground closure.
Referring to Fig. 9 to Figure 11, these attached drawings respectively in show device 10, turn including substantially as illustrated in fig. 1 and 2
Son 12 has the support construction including bracket 60.Each rotor 12 is supported on axis along its rotation axis 14, each axis
Opposite end is supported by bracket 60, but each bracket limits vertical slots 62, the end of axis can in 62 vertical sliding of vertical slots, with
Move up and down rotor 12.
The construction of the support construction for the rotor 12 that can be used for supporting in use be it is unlimited, and structure can be it is geographical quiet
(such as bracket 60) only can be floated by other object supports.In addition, bracket 60 shown in figure respectively allows
Rotor 12 is along 62 vertical shift of slot, but in other embodiments, rotor can in a manner of various other vertical shift or
Their height can fix.
No one of rotor 12 shown in Fig. 9 to 11 has preceding hole in their pipe 18, but this is only coincidence,
And the rotor with preceding hole can be used in any one of these embodiments.In addition, the rotor 12 in only Figure 11 exists
There is valve, but this is also only that rotor shown in coincidence and Fig. 9 and 10 also can have valve on its uropore 24.
Referring to Fig. 9, the alternating current generator 64 of sealing is arranged on one end of armature spindle 58, and is configured to through rotor
Rotation generates electric power-and therefore avoids the needs for transmitting power from device 10.4.Float 68 is provided to control and turn to provide buoyancy
The height (seeing below) of son 12, and float includes in the float of the either end floating of rotor and in the opposite of alternating current generator 64
Float two floats for side, to compensate the weight of alternating current generator.
Referring to Fig.1 0, rotor 12 includes wheel 20, and each wheel has groove, belt or other on its excircle
Flexible transfer member may be housed in the groove, and power is transmitted to slave equipment from wheel.The both ends of rotor 12 have floating
Son 68.
Referring to Fig.1 1, other than with valve, rotor 12 and bracket 60 are identical as shown in Figure 10, but in addition, dress
Setting 10.6 includes the alternating current generator 64 being supported on alternator support 70, and alternator support 70 is by the one of rotor 12
A wheel 20 is driven by belt 72.The tension on belt 72 is kept by free pulley 74, free pulley 74 can be in alternative electric generation
Horizontal sliding in machine support 70.However, in other embodiments, the levels of actuation sliding of free pulley 74 can replace float 68 or
Person is other than float 68 for raising and reducing rotor 12.
Referring to Fig. 9 to Figure 11, the vertical position (height) of each rotor 12 (such as can pass through free pulley 74 by actuating
Movement) or the buoyancy by controlling float 68 control.In a preferred embodiment, buoyancy opens and closes float by timing
On valve with air is discharged and allow water to enter float, water is discharged and allow air into float or keep content and because
This keeps the density of float to control the position of float 68.
When the main operating modes of rotor 12 are impingement flows, either from water flow 42 or from wind 44, it is intended to
Rotor is maintained at the optimum height relative to the water surface 30, how to be changed but regardless of the water level from tide and/or wave.Especially
Be, when the impact from water flow 42 is the major impetus of rotor 12, then preferably remain rotor submerge its height about three/
One (as shown in Figure 5).Therefore, in these cases, when water level changes, rotor 12 is preferably allowed for move up and down along slot 62,
And if float 68 has correct buoyancy rotor 12 is maintained at optimum depth, this point may be implemented.
Persistently have after operating each change of the rotor 12 only between submerged position and raised position by mass shift
The period of limit, and when rotor is increased or is totally submerged completely, rotor is sequentially with the execution of mass shift mode.Rotor 12
Be totally submerged and can be realized by the way that air is discharged from float 68 so that their loss of buoyance and rotor " sinking ", still
Buoyancy by individually controlling float can not achieve the complete raising of rotor.On the contrary, in addition, rotor 12 submergence or raising
It can be by allowing rotor as the variation of water level 30 raises and reduces and the selectively vertical position of locked rotor, together
When allow water level to be increased to above rotor or be reduced to below rotor.
The operation of device 10 is not necessarily such case preferably by computer long-distance control.In addition, the behaviour of device 10
Make to optimize for each position, and may be adapted to most preferably utilize available energy-in most cases, this
It will change over time.Particularly, some form of energy that can be obtained by device 10 is relatively predictable, such as tide
Stream.Other energy may less can be predicted, but can moderately adjust, for example, the flow in river may be it is uncertain, still
The predetermined portions of stream can be guided to provide the uncertain wind of scheduled flow or direction and can be guided along preferred
Direction is impacted on rotor 12.However, some energy sources are more difficult to predict, for example, wave height and monsoon intensity, and in order to most preferably
Using these energy, the operation of device 10 may need to be adjusted as needed.It is one advantage of the present invention that device 10
Multifunctionality, to obtain energy from the mobile fluid of various modes.
For example, device 10 may be mounted at rotor be exposed to wave and tide position-its can supplement wind-force work
With, but for simplicity, wind effect is omitted in this example.If without apparent wave action, but existed aobvious
Air can be partly discharged from float 68 then to support rotor 12 to submerge the one third of its height (with water in the tidal water flow of work
Position it is unrelated) and it will by tidal current 42 impact blade 26 and rotate.
When tide is close to the time of low water, rotor 12 can be locked against the slide downward in slot 62, and when tide returns to
Water level further declines at ebb tide.If necessary to increase buoyancy, this will allow the water from float to be discharged under the effect of gravity.Separately
Outside, locked rotor 12 is to prevent slide downward from be increased to it when tide is decorporated above water level 30, so that it can be to rise
High mode operates (as shown in Figure 4).Therefore, when tidal current is relatively small, the operation under lift mode can be on the ebb
Shi Jinhang.
Once water is discharged with lift mode from the chamber in pipe 18, rotor 12 can be under the effect of gravity along slot 62 to downslide
It is dynamic, and (if necessary) can be discharged from float 68 in air, so that rotor is to be supported again by the buoyancy of floating material,
Energy is obtained from tidal current 42 with level appropriate, midway of the tidal current 42 between low tide and climax becomes stronger.
When tide is close at high tides, rotor 12 can be locked against the upward sliding in slot 62, while water level continues
Rise to flood tide and water immersion rotor.In submergence, rotor 12 can work as tide to submerge mode operation (as shown in Figure 3)-
When flowing relatively small, it will occur at high tides.
For one denier air from the chamber discharge in the pipe 18 in submergence mode, rotor can be under the buoyancy of float 68 along slot 62
Upward sliding, to restore its height, the there tidal current of its available retrogressing relative to water level 30.
If wave action increases to the energy that can be obtained from tidal current from the energy ratio obtained in wave action more
More degree, then rotor 12 can lock (this relative to slit 62 at the intermediate altitude between the peak value and trough of wave
It will need to be adjusted once in a while to compensate the tidal fluctuations of mean water).When wave wash device 10, rotor 12 is alternately immersed in
It in wave crest and is increased to above trough, and it is with submergence and raised mode blocked operation.If desired, uropore can be opened
Valve on 24 is to increase mass transfer rates, because the frequency of wave is much higher than the frequency of tide, and mass transfer rates need
It is synchronous most preferably to obtain Wave energy with this increased frequency holding.If rotor 12 has preceding hole 46, they can also be with
It is selectively opened to increase mass transfer rates, as described above.
Referring to Fig.1 2 and 13, the device of the 7th and the 8th embodiment respectively includes rotor 80 according to the present invention, and rotor 80 wraps
Four chambers 82 are included, chamber 82 is connected to hub 84 by hollow conduit 86.Each chamber 82 is hollow and limits inner chamber,
Each conduit 86 limits inner passage, which is in fluid communication on this catheter with the chamber in chamber 82, and with hub 84

Entrance be located at wheel hub, the outlet of passing away highly preferable lower than wheel hub (and rotation axis) and surely not more
It is high.
Rotor 80 is supported by support construction (not shown), and support construction is immersed in the main body of dense fluids, along rotation
Turn direction 16 to rotate around approximate horizontal rotation axis 14.Device 10.7 and 10.8 can be used for various fluids, but herein
Its purposes is described with reference to the dense fluids of the form of water and the low density flow of air form.Since rotor 80 is supported on
In water and passing away extends to the air lower than wheel hub from wheel hub, therefore must have air near water, of the invention this
A embodiment is suitable for having the water body of air, such as dam or reservoir near water, wherein rotor 80 can be immersed in dam or
In reservoir, passing away can extend to the position outside wall from the wall that wheel hub 84 passes through dam or reservoir.
Four chambers 82 are in different radial oriented relative to rotation axis 14, and in each example shown,
Four chambers are spaced apart with right angle.However, will usually provide and be spaced apart more around axis 14 for the optimum operation of rotor 80
Multi-chamber.In addition, the conduit 86 shown in figs. 12 and 13 has equal length, but such case is needed not be, rotor 80
It may include multiple chambers 82 with axis 14 at different radii.
Chamber 82 shown in Figure 12 is usually tear drop shape, has a circular front end and conical tail end, and institute in Figure 13
The chamber shown is usually discoidal.In both cases, chamber, which is all shaped as, makes it while rotating around axis 14
To the drag minimization of water.
Referring to Fig.1 4, the schematic diagram of rotor 80 is shown, rotor 80 includes eight chambers 82 and eight conduits 86, such as Figure 12
It is shown.Chamber 82 and conduit 86 preferably with the configuration that is staggered (similar to Figure 12 rotor with staggered side-by-side arrangement
It shows).
Chamber 88 is limited inside each chamber 82, and in each conduit 86, limit inner passage 90, the inner passage
90 are connected to the indoor chamber of the chamber for being connected to the conduit.Each chamber 82 is also limited in front-rear position relative to direction of rotation respectively
Preceding hole 92 and uropore 94.Channel 90 link together at wheel hub 84 and therefrom along public passing away (be not shown, but
Indicated by circle 96) extend.
Each channel 90 can be selectively closed off by channel valve 98, and channel valve 98 is preferably provided near chamber 88.
In addition, each preceding hole 92 has preceding ports valve 92, and each uropore has uropore valve 94, to open and close preceding hole and tail respectively
Hole.(preceding hole and preceding ports valve are identified by appended drawing reference 92, and similarly, and uropore and uropore valve are identified by appended drawing reference 94,
To reduce the confusion in Figure 14.) even if chamber is identical, each chamber in Figure 14 around axis 14 its rotation different phase
It shows, therefore each chamber/position is also used for the feature of identification particular chamber by suffix mark-suffix.Valve is shown when closed
For " X ", " O " is shown as when opening.
In use, when position shown in chamber 82 reaches 82.1, preceding ports valve 92.1 and uropore valve 94.1 are closed,
Channel valve 98.1 is opened.Therefore, chamber 88.1 is connected to its channel 90.1 and passing away 96.1, so that any in chamber 88.1
Elevated pressures are released, and its internal pressure is reduced to the environmental air pressure in the exit of passing away 96.Moreover, chamber
Water in 88.1 is discharged under the effect of gravity by channel 90.1 and passing away 96, and is released from the passing away outside dam wall
It puts.Therefore, chamber 88.1 quickly fills with air, and when chamber 82.1 rotates upwards, capture is also fast in any water of its tail end
Speed discharge.
When chamber 82 rotates to the position as shown in 82.2, all water is all discharged from its chamber 88.2 and full of sky
Gas.When chamber 82 reaches the position 82.3 at 80 top of rotor, situation is still such.At this point, channel valve 98.3 is closed, hereafter not
Long, it is rotated with chamber 82 towards position shown in 82.4, preceding ports valve opens 92.4, moves the water to flow into chamber 88.4.It should be kept in mind that
Water around rotor 80 is preferably due to the head above it and under sizable pressure, and water is flowed by preceding hole 92.4
Enter the pressure increased in chamber 88.4 in chamber 88.4, makes it equal to the hydraulic pressure of surrounding.Water except through preceding hole 92.4 flows into it
Outside, rear ports valve 94.4 is also opened, this makes air from the water that chamber 88.4 escapes into surrounding.The final result of these steps is water
It soon flows into chamber 88.4 and is continued as chamber 82 is rotated down by position shown in 82.5 and 82.6 to 82.7.
During the position (being shown as position 82.7 to 82.1) for rotating to the left side from the position of 80 bottom of rotor, in chamber
